Folded opening-resistant container

ABSTRACT

A folded opening-resistant container includes a cover body, which has an outside that is provided with a grip part, which is connected, in an inside thereof, through a perforation line to a first engaging member; and a box body, which includes a circumferentially surrounding wall and a bottom plate arranged at a bottom inside the wall. A foldable member extends from a top end of the wall. The foldable member has an end that is provided with a second engaging member. The cover body and the box body are combinable and interlockable in a detachable manner. The foldable member is curvable or flexible to allow the second engaging member to engage and combine with the first engaging member, such that when the cover body and the box body are separated, the perforation line is broken and the first engaging member and the cover body are separated from each other.

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a container, and more particularly to afolded opening-resistant container that is resistant against opening andis unrestorable upon opening.

DESCRIPTION OF THE PRIOR ART

Various plastic containers that are made through vacuum forming areavailable, including boxes, cups, or bowls, for packaging food to keepthe food fresh in supermarkets. Such products are generally made ofclear materials, allowing general consumers to observe food therein inpurchasing products in order to eliminate unnecessary arguing andquarrels after the sale. However, to inspect the food contained in sucha container is intact and fresh, some consumers may open, withoutpermission and authorization, the plastic container to directly inspectthe food, and often, such products are not or cannot be restored to theoriginal condition after such opening. This would lead loss of freshnessfor the food contained in the plastic container, and the plasticcontainer is damaged and the outside appearance is affected. Further, ifit is not timely recognized that the package container has been opened,the food contained therein may get deteriorating and this would cause awaste of food and is also an economic burden of the shops. In view ofthe above, the present invention aims to provide a foldedopening-resistant container, which achieves the purpose of openingpreventing, opening recognizing, and unrestorability upon opening, inorder to alleviate or overcome the drawbacks of the prior art and toimprove the performance thereof.

SUMMARY OF THE INVENTION

In view of the above drawbacks, the present invention provides a foldedopening-resistant container, which comprises: a cover body, which has anoutside that is provided with a grip part, the grip part beingconnected, in an inside thereof, through a perforation line to a firstengaging member; and a box body, which comprises a circumferentiallysurrounding wall and a bottom plate arranged at a bottom inside thewall, a foldable member extending from a top end of the wall, thefoldable member having an end that is provided with a second engagingmember, the cover body and the box body being combinable andinterlockable in a detachable manner, the foldable member being curvableor flexible to allow the second engaging member to engage and combinewith the first engaging member, such that when the cover body and thebox body are separated, the perforation line is broken and the firstengaging member and the cover body are separated from each other.

In a known female-male fastener structure of a container, the malefastening member is made with a male mold and thus exhibits a highstiffness, while the female fastening member is made with a female mold,making a bottom thereof insufficient in stiffness, such that when themale and female fastening members engage and combine with each other,the male fastening member can be easily ejected out through pushing thebottom of the female fastening member so as to readily open the cover.The present invention is structured such that the first engaging memberand the second engaging member are both made with a male mold, and assuch, the stiffness is enhanced for both the first engaging member andthe second engaging member. Due to the high stiffness of the firstengaging member, it is not possible to eject the second engaging memberout by pushing the bottom of the first engaging member, and thus, thedrawback of the prior art female-male fastener structure is overcome.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

For easy description of the contents of the present invention, and theeffectiveness achieved thereby, an embodiment is provided, incombination with the attached drawings. As shown in FIGS. 1-3 , thepresent invention provides a folded opening-resistant container, whichcomprises:

a cover body 10, which is provided, on an outside thereof, with a grippart 11, wherein the grip part 11 is connected, at an inside thereof,through a perforation line 111 to a first engaging member 12;

wherein, referring to FIGS. 3 and 6 , the grip part 11 comprises a notch112, and the first engaging member 12 is connected through theperforation line 111 to the notch 112; and

a box body 20, which comprises a wall 21 that is circumferentiallysurrounding and a bottom plate 22 arranged on a bottom of an inside ofthe wall 21, wherein a foldable member 211 is extended from a top end ofthe wall 21 and the foldable member 211 is provided, at a distal endthereof, with a second engaging member 212.

The first engaging member 12 and the second engaging member 212 comprisea planar part A and a fastening part B. The planar part A of the firstengaging member 12 is connected, at one side thereof, through theperforation line 111 to the grip part 11 of the cover body 10, andspecifically, the planar part A of the first engaging member 12 isconnected through the perforation line 111 to the notch 112.

The planar part A of the second engaging member 212 is connected, at anend thereof, to the foldable member 211, wherein the foldable member 211is formed with a first fold line 2111 and a second fold line 2112 thatare spaced from each other, and the first fold line 2111 is connected tothe end of the planar part A of the second engaging member 212.

The fastening part B is made in the form of a hollow cylindrical bodyhaving a top end that is formed with an opening B 1, wherein an outsideof the opening B1 is combined with the planar part A.

An interior and the outside of the fastening part B are made in aconfiguration that is narrow in top and wide in bottom, but is notlimited thereto.

Referring to FIGS. 3-5 , the cover body 10 and the box body 20 arecombinable and interlocked in a detachable manner. The foldable member211 is curved or flexed to have the second engaging member 212 engagingand combined with the first engaging member 12 in such a way that theoutside of the fastening part B of the second engaging member 212 issnap fit into and engages with the opening B1 of the fastening part B ofthe first engaging member 12, wherein the fastening part B of the secondengaging member 212 extends through the opening B1 of the first engagingmember 12 into the interior of the fastening part B, such that thefastening part B of the first engaging member 12 is set in tight andretaining engagement with the fastening part B of the second engagingmember 212.

Referring to FIG. 6 , to open the folded opening-resistant containeraccording to the present invention, a user uses two hands torespectively grip the grip part 11 and the interlocked first and secondengaging members 12, 212 and lift upward and thus open the cover body 10so that the perforation line 111 is broken and thus, the cover body 10and the box body 20 are separated from each other, wherein the firstengaging member 12 so torn away is not re-combinable with the notch.
